Connecticut HVAC Exam Prep: 1,450 Practice Questions for the S-1 Unlimited Heating, Piping and Cooling Contractor License
PassProfessor’s Connecticut HVAC Exam Prep is built for candidates for Connecticut’s S-1 Unlimited Heating, Piping and Cooling Contractor license, issued by the Department of Consumer Protection. The bank holds 1,450 original practice questions: a 1,250-question HVAC core covering the trade itself, plus 200 Connecticut questions on Connecticut law, business and law, and trade application.
Every question is an original item written for this program, and every question comes with an explanation for every answer: why the keyed answer is right and why each other option is wrong, grounded in the cited code, standard, manual, or rule.
The exam, in facts
- The S-1 is Connecticut’s unlimited heating, piping, and cooling contractor license under Title 20, Chapter 393 of the Connecticut General Statutes, administered by the Department of Consumer Protection. Its scope includes sheet metal work; it does not include electrical or plumbing work, which sit in their own license types.
- Qualification runs through the journeyperson tier: an S-1 applicant shows 2 years as a properly licensed journeyperson, or the equivalent – 576 classroom hours plus 12,000 hours of on-the-job training through a registered apprenticeship or its evaluated equivalent.
- Connecticut licenses expire annually on August 31, and the Department of Consumer Protection publishes no continuing-education requirement for the S-1 license.
- Connecticut holds no reciprocal agreements with any other jurisdiction for these licenses – the Department states this flatly, so licensure here runs through the Connecticut route itself.
- The code Connecticut’s heating and cooling work answers to is the 2022 Connecticut State Building Code, built on the 2021 International Mechanical Code as amended for Connecticut, with the NEC 2020 for electrical work. Connecticut has adopted no statewide fuel gas code.
How the practice program works
The full practice exam draws 100 questions on a 180-minute practice clock. Connecticut’s S-1 materials publish no exam count or time limit, so the draw and the clock are this program’s practice convention. The exam spans the bank’s 19 topics, and every attempt draws a fresh assortment, so no two practice exams are the same.
Each of the bank’s 19 topics has its own drill, so you can drill Connecticut licensing law on its own or work the trade topics one at a time:
- Refrigeration Principles & Components — 114 questions
- Refrigerants, Recovery & Handling — 55 questions
- Cooling Systems: Service, Diagnostics & Repair — 91 questions
- Heating Systems — 212 questions

Our practice exam is scored against a 70% practice benchmark. Connecticut does not publish a passing score for the S-1 examination in the materials this program is built from, so 70% here is a PRACTICE BENCHMARK ONLY – a study signal, not a state standard and not a result on the real exam.
Questions
Which Connecticut license does this cover?
The S-1 Unlimited Heating, Piping and Cooling Contractor license. Connecticut’s ladder runs apprentice, journeyperson (S-2), then contractor (S-1); the limited contractor licenses (S-3, S-5) and the solar thermal types sit outside this program’s scope.
Is the practice exam timed like the real one?
The full practice exam runs 100 questions on a 180-minute practice clock. Connecticut’s published S-1 materials do not state the examination’s question count or time limit, so this clock is our practice convention, not a mirror of a published exam format.
Are these real exam questions?
No. Every question is original to PassProfessor, written from Connecticut’s published licensing materials and the trade’s standard references. Nothing here is copied or paraphrased from a licensing exam or a competitor’s bank.
What does the 70% benchmark mean?
Our practice exam is scored against a 70% practice benchmark. Connecticut does not publish a passing score for the S-1 examination in the materials this program is built from, so 70% here is a PRACTICE BENCHMARK ONLY – a study signal, not a state standard and not a result on the real exam.
